Is Food In The Refrigerator And Freezer Safe To Eat After A Power Failure?

By Leave a Comment

Your power is out. What should you do with all that food in your fridge and freezer?

The Basic Rules For Leftovers

According to the March 2010 edition of the Nutrition Action Healthletter (Center for Science in the Public Interest), you should follow these general rules:

  • The mantra is:  2 Hours–2 Inches–4 Days
  • 2 Hours from oven to refrigerator: Refrigerate or freeze your leftovers within 2 hours of cooking. Throw them away if they are out longer than that.
  • 2 Inches thick to cool it quick: Store your food at a shallow depth–about 2 inches–to speed chilling.
  • 4 Days in the refrigerator–otherwise freeze it:  use your leftovers that are stored in the fridge within 4 days. The exceptions are stuffing and gravy– which should be used within 2 days. Reheat solid leftovers to 165 degrees F and liquid leftovers to a rolling boil. Toss what you don’t finish.

Food Safety

The following food safety information is from the CDC:

  • If power is out for less than two hours food in the refrigerator and freezer will be safe to eat. While the power is out keep the refrigerator and freezer doors closed as much as possible.  This helps to keep food cold for a longer period of time.
  • The refrigerator will keep food safely cold for about four  hours if it is unopened. A full freezer will hold the temperature for approximately 48 hours (24 hours if it is half full) if the door remains closed.
  • If power is out for longer than 2 hours follow these guidelines:
    • Freezer:  “A freezer that is half full will hold food safely for up to 24 hours. A full freezer will hold food safely for 48 hours. Do not open the freezer door if you can avoid it.”
    • Refrigerator: “Pack milk, other dairy products, meat, fish, eggs, gravy, and spoilable leftovers into a cooler surrounded by ice. Inexpensive Styrofoam coolers are fine for this purpose. Use a food thermometer to check the temperature of your food right before you cook or eat it. Throw away any food that has a temperature of more than 40 degrees Fahrenheit.”

Can Thawed Or Partially Thawed Food In The Freezer Be Frozen Again?

According to the USDA:  “food may be safely refrozen if the food still contains ice crystals or is at 40 °F or below. You will have to evaluate each item separately. Be sure to discard any items in either the freezer or the refrigerator that have come into contact with raw meat juices. Partial thawing and refreezing may reduce the quality of some food, but the food will remain safe to eat. See the attached charts for specific recommendations.”

What If Flood Water Covered Food Stored On Shelves And In Cabinets? 

According to the USDA follow these guidelines for what can be kept or should be thrown out:  “Do not eat any food that may have come into contact with flood water. Discard any food that is not in a waterproof container if there is any chance that it has come into contact with flood water. Food containers that are not waterproof include those with screw-caps, snap lids, pull tops, and crimped caps. Also, discard cardboard juice/milk/baby formula boxes and home canned foods if they have come in contact with flood water, because they cannot be effectively cleaned and sanitized.”

Leftover Dilemma: Can I Eat It Or Should I Toss It?

By 1 Comment

You know the feeling:  you’re standing in front of your open refrigerator. There’s a mess of containers in there. Move ‘em around. Discovery: A mystery plastic container all the way in the back; a couple of Chinese food take-out containers; some oddly shaped tin-foil packages. Don’t you wonder what’s in them?

With some trepidation you take a peek. Container #1: the leftover take-out chicken fried rice from five days ago. Container #2: the rest of your lasagna you brought home last night from a huge restaurant portion. Then there’s some of Mom’s really delicious stuffing from last weekend in that plastic container.  The tin-foil packages: grayish looking stuff that doesn’t smell so great.

Big question: Will you end up writhing in pain and spending the next day in the bathroom if you eat any of it?

How Long Can Prepared Food Safely Stay  Unrefrigerated?

According to the FDA, when you buy hot, cooked food, you should get it home quickly and eat it right away.  It shouldn’t sit out at room temperature. If the food is cold – not hot — and sitting out, it should be eaten within two hours of when it was prepared.  Otherwise, store it in the fridge, or freeze it.

Take-Out Food

When take-out food is delivered, you want to prevent any lurking potentially nasty and harmful bacteria from multiplying, so eat the food within two hours after it arrives. If you aren’t going to eat it within two hours keep it hot in an oven set at or above 200° F (93° C). Side dishes also should to be kept hot in the oven. Cover the food to keep it moist while you’re keeping it warm. Don’t guess at the temperature of the food. Use a food thermometer to check that the food is kept at an internal temperature of 140° F (60° C).

The Food Temperature “Danger Zone”

The FDA defines the “danger zone” as the range of temperatures at which bacteria can grow. It is usually between 40° and 140° F (4° and 60° C). To keep food safe, it’s important to keep it below or above the “danger zone.”

The 2 Hour Rule For Leftovers

There is a 2 Hour Rule: toss any perishable food (the kind that can spoil or become contaminated by bacteria if left unrefrigerated) that has been left out at room temperature for more than two hours. When the environmental temperature is above 90° F (32° C), throw out the food after one hour.

The Center for Science in the Public Interest’s Nutrition Action Healthletter, expands on the Rules For Leftovers with what they call:

2 hours – 2 inches – 4 days

2 hours from oven to refrigerator: any leftovers should be refrigerated or frozen within 2 hours of cooking or they should be thrown away.

2 Inches thick to cool it quick: food should be stored in containers at a shallow depth of about 2 inches or less, to speed the chilling time.

4 days in the refrigerator or freeze it: use refrigerated leftovers within 4 days — with the exception of stuffing and gravy which should be used within 2 days. Solid leftovers should be reheated to 165 degrees F and liquid leftovers to a rolling boil. Whatever you don’t finish, throw out.

What About The Doggie Bag?

If you leave a restaurant with a doggie bag – or a prepared food store with a container of food – and you’re not going to get home within two hours of having the order served to you, scrap the food. If you do leave with doggie bag or food container in hand, keep in mind that the inside of your car can get very toasty and bacteria can multiply very quickly. So, if the doggie bag contains tomorrow’s lunch or a late night snack, it’s a good idea to go directly home and get those still identifiable leftovers in the refrigerator right away.
